Musician and activist Wyclef Jean has entered a New Jersey hospital to treat what is being described as stress and fatigue. “Wyclef Jean has had an extremely grueling three months — truly an exhausting eight months, since the earthquake when he recommitted himself to our homeland and his passion for our people,” his family said in a statement. “He is currently suffering the effects of lack of sleep and stress, global travel, even the endless public eye, and has asked that his fans and supporters bear with him for the next several days as he regains his physical health and stamina. Then he will be back out in front of the crusade to rebuild Haiti and his pledge to make it even better for business.” Jean, 40, had planned to mount a campaign for president of Haiti until election officials rejected his bid last month. Last week he officially withdrew from the race.
